Audio combo jack vs headphone/earphone with mic and speaker connector
I see the audio combo jack in my T510 (indicated number 6 in the image), but I've used a regular headphone in it without plugging in the mic connector.
1. How do I hook up a regular microphone - does the port "know" the difference between 2- or 3-conductor microphone plug and a stereo headphone plug?
2. How do I use a headset with separate mic and speaker connections? Is there an adapter I need?
You may have two options:
Get a new headset with combo jack or
Purchase an adapter that can connect your current headphone with mic and speaker back to the machine audio combo jack.
The good thing about the combo jack is that it works with the hundreds of 3.5mm phone headsets which a lot of people already carry. There is a wide range of choice at all cost and quality levels (newer Blackberry, iPhone, etc. headsets).
On the other hand, anyone with an exisiting separate mic and headphones will have a problem. A simple adapter solves this problem. See the threads in "Related Links" to the right for examples of adapters which community members are using.
